[Maxima] Operations on inf

Currently, maxima does interesting things like 4*inf -> 4*inf, inf/inf
-> 1, etc.
I have hacked on this a bit and maxima now says:
4*inf -> inf
-1*inf -> minf (debatable?)
inf/inf -> und (or ind?)
inf*inf -> inf
inf*0 -> und (or ind?)
(1-sqrt(2))*inf -> minf
(1+sqrt(2))*inf -> inf
But inf^2 -> inf^2, still, and x*inf -> x*inf. I wasn't sure what to
do with x*inf, so I thought it best to leave it alone.
I'm sure there are other cases to consider.
Is this the direction we want Maxima to go in?
